ABSTRACT:
A optical fiber connector cord capable of being detachably attached to a receptacle fixed to an optical apparatus includes an optical fiber having at least one hole which extends along an optical axis, a plug having a fiber hole through which the optical fiber extends and which is capable of being fitted into the receptacle, a first sealing member which is provided on an outer peripheral surface of the plug and which seals a gap between the plug and the receptacle along the outer periphery of the plug, and a second sealing member which seals a gap between an inner surface of the plug's fiber hole and the optical fiber along the outer periphery of the optical fiber, so that holes in the optical fiber are effectively prevented from communicating with the atmosphere. In addition, an optical coupling set includes the optical fiber connector cord and the receptacle.
